- They are running right up on the timeline to make the 30th because once the Falcon 9 and integrated payload are vertical at 39A, they need 13 hours to check out the spacecraft. Might be a slip to 3–31.

- The launch window was shortened to 1800 – 2030 EDT not because of the vehicle or SpaceX, but because the FAA didn't want to close down airspace for a 4hr launch window.

SpaceX is targeting launch of SES-10 from historic Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. The two and a half hour launch window opens on Thursday, March 30, at 6:27 p.m. EDT, or 10:27 p.m. UTC. The satellite will deploy approximately 32 minutes after launch. A backup launch window opens on Saturday, April 1, at 6:27 p.m. EDT, or 10:27 p.m. UTC.
